Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to audio equipment such as radios installed in automobiles, and more specifically, the invention relates to audio equipment such as AM radio, FM radio, cassette, compact disk, television, etc. as audio sources. , relates to a car audio system having multiple audio sources.

(Prior Art) Cars have traditionally been equipped with audio equipment such as radios, but recently the types of audio equipment have diversified into AM radio, FM radio, cassette decks, etc. There is.
When multiple audio sources are installed in one vehicle,
It is not possible to output sounds from multiple audio sources at the same time in a small vehicle interior, so it is necessary to be able to select and switch between a single audio source. For this reason,
For example, as disclosed in Japanese Patent Application Laid-Open No. 55-120228, each audio source can be turned on and off independently, and the audio source turned on later can be operated with priority, and other audio sources can be turned on and off. A power supply operation circuit that turns off the power supply has been proposed.

On the other hand, recently, a system has been proposed in which a speaker called a pillow speaker is provided in each seat of a car near the passenger's ear, so that each passenger can hear audio from a separate speaker. When equipped with this pillow speaker, each passenger can independently select one of multiple audio sources, allowing each passenger to hear audio from different audio sources in one vehicle. This happens. In this case, it would be better to provide an audio source selection switch that each passenger can operate individually, so that each person can freely select the audio source, but the operation within the selected audio source, for example, AM radio Since it is not possible to select a different station for each crew member, when multiple crew members select the same audio source, it is difficult to determine how to perform operations within that audio source. It becomes a problem. If each crew member is allowed to perform this operation freely, for example, when crew member 1 selects a certain station and listens to it,
If another crew member switches to another station using the same audio source without knowing this, the first crew member will suddenly be switched from the station they were listening to to another station, causing an unpleasant experience. This is not desirable.

(Purpose of the invention) The present invention was made in view of the above-mentioned circumstances, and it is an object of the present invention to provide an audio system for an automobile that allows each passenger to know in advance the selection status of the audio source for each seat. The purpose is to

(Structure of the invention) The sound device of the invention is provided with a pillow speaker and an audio source selection switch in each seat, so that each passenger can select the audio source separately, and A display section that displays all the selected audio sources for each seat is provided near each of the audio source operation sections provided in the rear seats, so that each passenger can know in advance the selection status of the audio source for each seat. It is characterized by the following.

(Effects of the invention) According to the invention, each passenger can know in advance the selection status of the audio source at each seat, so they can avoid accidentally operating the audio source that others are listening to, for example, turning off the audio source. This prevents the user from switching to another station or selecting another station using that audio source, thereby preventing others from experiencing unpleasant feelings.
